I'm stumped here guys and could use some help. I need to add a 2" washing machine drain to the setup shown below. There is a 3" vertical drain line and a 2" vertical vent line that I need to tap into.
I can't figure out how to pipe in the drain....here are my problems. The pipes are in between the studs. I want to use a flush mount washer drain box. I want the drain to be to the left of the 3" line.
Any help here...I can if needed fir out the wall with 2X's on their side.
